Added a VIA. Now it's time to find out how poor my 6522 emulation is.

Made an almost complete implementation of video. Just one row of the diagnostics cartridge seems to be off, showing thw wrong character set.

Made some basic first attempt at parsing video attributes; ensured lowest byte of ROM is readable.

Meaningful text! Albeit with the initial 'O' of 'Oric' missing. I guess control codes and NMIs next?

Switched to using a diagnostic ROM for now, as it'll definitely boot without initially requiring either a 6522 or AY. Have some forms appearing which imply I'm not doing badly, at least up to not knowing where I'm supposed to get character pixels from.

Made a faulty but hopefully creditable attempt to demarcate an Oric frame.

Added just enough wiring to add something that will generate the video, one day.

Ensured that the ROM gets installed. So next for some video action?

Added enough wiring to get Oric TAPs through to a completely unimplemented Oric emulation.
